Fidji Simo has resigned from her full-time position as head of artificial general intelligence at OpenAI, shifting to a part-time advisory role. The Wall Street Journal reports the decision follows a worsening of her medical condition, which had already placed her on extended leave.
The departure removes a key figure from OpenAI's leadership just as the company prepares for an initial public offering. Simo led the AGI team, a division focused on the company's most advanced and speculative AI research.
According to the Journal, Simo will not return from her medical leave. Her transition marks one of the most significant leadership changes at the AI giant in recent months.
The executive's exit introduces uncertainty around OpenAI's AGI roadmap during a critical fundraising and IPO preparation phase. The company has not announced a permanent replacement.
OpenAI declined to comment beyond the details reported by the Journal regarding Simo's departure.
